1 Pick a world

Every world is drawn by code, from a small description of its lands, plants, animals, people and villages. Tap one to choose it. Leave 3D depth on to see the world with heights, walls and standing houses and trees; turn it off for the flat, top-down pixel style.

Step 1: the list of worlds, with the 3D depth switch on
The worlds, top-down ones first. The tea village is chosen.

1b Or describe your own

Choose Describe one, write a line about your world and press Make the world. Two ways to have it made:

Step 1b: describing a world, with the Slow and Fast choices
"A misty fishing town on a bay, with a lighthouse and crab merchants."

2 Pick a kind of game

Ten kinds: explore and collect, photo safari, hidden object, fishing, quiz, creature keeper, point and click, island explorer, and (on side-view worlds) the runner and the racer. A kind that does not fit the world you picked is greyed out and says why.

Step 2: the kinds of game

3 Tune it

A few sliders for the kind of game you picked (how many things to find, how far the world goes, a time limit), plus the season, the weather and a seed (a different seed makes a different arrangement of the same world).

Step 3: the sliders

4 Your data (optional)

Drop in a file of questions and answers (CSV or TSV, a header row naming them) and the quiz asks your questions. You can also write an idea for the game; with a model, it shapes the game's goal and its lines.

Step 4: your data

5 Play

Press Play. Click the game, then press Space or tap to start.

Step 5: the game's title card in the preview
Playing: the tea village in 3D
Playing in the tea village, in 3D.

6 Download

Press Download game. You get one HTML file: open it in any browser, even offline, and send it to anyone. It has the whole game in it, the world and its drawing included.

Step 6: the download button
